METALLIC BARREL.

Specification of Letters Patent.

Patented Feb. 25, 1913..

Application filed June 24, 1912. Serial No. 705,632.

To all whom it may concern:

Be it known that I, DAvInB. GALBALLY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Metallic Barrels; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to metallic barrels, and has for its object to produce such barrels from individual staves, while firmly locking them together in a more efiicientand less costly manner than has heretofore been practical.

To these ends the invention consists in the novel combinations of parts and details of construction more fully hereinafter disclosed and particularly pointed .outin the claims.

Referring to the accompanying drawings forming a part of this specification, in which like numerals designate like parts in all the views: Figure 1 is a diagrammatic view, illustrating a pair of fiat staves placed edge to edge preparatory to being curved to shape. Fig. 2 is a view similar to Fig. 1, illustrating the operation of forcing the locking strip over the meeting edges of the staves in order to bind them together and simultaneously curve them to shape. Fig. 3 is an enlarged sectional view, in perspec tive, of the joint formed between the staves.

Fig. 4 is a view similar to Fig. 3, but illus-.

trating the flanged head portion of the barrel. Fig. 5 is a top plan view of the barrel, without the top; and Fig. 6 is a longitudinal sectional view of a completed barrel employing my joint.

1 indicates fiat staves cut from fiat metal sheets by any suitable means. These staves are provided along their ends with the oifset flanges 2, providing the seats 3 for the head 4, and have along their longitudinal edges the locking flanges formed by turning up said edges, by any suitable means, so

that each, when in the position shown in Fig. 3, will be composed of a vertical member 5, a horizontal member 6, a second vertical member 7 and a second horizontal member 8.

In order to firmly lock the flanges of two adjacent staves together, I provide the locking strip 22, formed from a single fiat piece of metal so bent upon itself that one edge, when in the position illustrated in Fig. 3, forms the horizontal member 9, fitting be tween the body 1 of the staves and the first horizontal member 6 of its locking flange. Said locking strip 22 is further, so bent as to provide the vertical member 10 extending at right angles to the member 9, and extending parallel to the member 7 of the locking flange when in contact therewith. The said locking strip is further bent so as to provide the second horizontal member 11, extending at right angles to the member 10, and bent again at right angles to the said second horizontal member 11 to form the second vertical member 12, and then bent at right angles to the said second vertical member 12- to form the third horizontal member 13. After being bent at right angles to form the third horizontal member 13, as above described, the material of the said locking strip 22 is next bent fiat back upon itself to form the fourth horizontal member 14:, which extendstwice the length of the said third member 13, whereupon it is again bent fiat upon itself to form' a fifth horizontal member 15, and then at right angles to the member 15 to form a third vertical member 16. From the member 16 the material of the locking strip 22 extends at right angles to form the sixth horizontal member 17 and then at right angles to the member 17 to form the fourth vertical member 18, and finally at rightangles to the member 18 to form the seventh horizontal member 19,

which constitutes the other edge of the said locking strip 22. I 1

In forming the locking flanges on the .staves l, the first vertical members 5 are made of a length just sufficient to cause the first horizontal members 6 to be located a distance away from the body of the stave 1 laid c. tor the snug acconunoda- 1 lion oi the horizontal members 9 and ot the locking strip \vhileih-e spaces left on said locking llanges between the horizontal incmhei's 6 and 8 are just sullicieut to snugly accommodate the parallel bent members 13 and 1t, and 1st and 1?), respectively, of the locking strip. Further the vertical uuanhers l2 and 16 oil the locking strip are chosen of proper dimensions to atlord cs adapted to snugly accommodate the horizontal members 8 of the locking flanges. it results from the structure just disclosed that when the carts are in the positions in dicated in Fig. 3, each member of the locking flanges is inclosed by one or more members of the locking strip 22, and that While the vertical members 5 of tvvo adjacent flanges are brought into contact to form a tight joint at it), the members .13, Ill and to constitute a firm brace or stittening rib which causes said joint to etl'ectually resist strains of all kinds that may be brought upon the linished barrel. Further it Will be observed that the slaves l are cut out of flat material with curved ed es. as shown. lit therefore i'ollo that it their curved edge-s are brought together as illustrated in l the said edges cannot meet in the .1 indicated by the dotted line 21, unless the oodies 01' said stavcs are curved into a concavo-convcx shape. But it ismturther evident. on the other hand, that if the said edges are briiiughl together, as illustrated. in la :2, and the locking strip driven or otherwise forced into the position as shown 3 to (3, then the curved edges of said llat stares 1 will be forced to meet in plane such as 21, and the body portions of said staves Will thereupon be torcechtoassume a concavoconvex shape as result of said driving action. Further the flexing of the stave bodies, in the manner indicated,

results in a Wedging action between the parts, as Well as in a setting up of stresses in the metal, causing the interlocking members o'l' the stairs hinges and locking strip .tobo put under a tension. It follows, as a. result of the complex tensioning strains thus set up, that a joint 20 of extraordinary tightness and stability is produced. In addition to the almve, this joint or seam 20. is bridged by the tightly fitting, longitudinally curved, bracing member l t, which further insures against leakage.

The entire construction offers no edges Which can be broken by bending or twisting while rolling the barrel, and it is found in practice to be the strongest part of the barrel. The locking pieces 22, after being driven home, are cut oil even with the seats 3, each end of the barrel, and their ends t'orm additional supports for the heads 4t.

ll. will also be observed that the longitudinally curved members llof the locking pierce which ln'idge' the seam 20, being lccated on the inside of the transversely and longitudinally curved staves, acts somewhat like the he the staves trom shitting after the hoops 24L are put on.

It is obvious that those skilled in the art may vary the details of (lOllSl'ltlCilOIl With out departing from the spirit of my inven tion, and therefore I do not Wish to be limited to the above disclosure except as may be required by the claims.

hat 1 claim is:

1. In a metallic barrel provided With a bilge, the combination of a plurality of longitudinally and transversely curved staves, each provided on their longitudinal edges with locking flanges comprising two horizontal and two vertical members forming recesses opening in opposite directions; with a locking strip with horizontal members adapted, when two opposing flanges are brought into contact, to snugly lit each of said open recesses and to firmly bind the said llanges together, substantially as described.

2. In a metallic bilge barrel, the combina tion of a plurality of curved staves each provided on each longitudinal edge With a locking flange, each flange having an outer recess opening toward the body of the stave, and an inner recess larger than said outer recess opening in an opposite direction, the said inner recesses of: tvvo opposing meeting hinges forming a single enlarged inner recess with a central radial opening; with a locking strip surrinmding said meeting locking flanges l'iaving opposing edges ontering the said outer recesses of said flanges, and having a bracing member fitting the said enlai cd inner recess of the opposing flanges, substantially as described.

in a metallic bilge barrel, the combination of a plurality of curvedsta-ves each provided on its longitudinal edges with looking flanges, each flange having outer and inner locking recesses opening in opposite directions; with a locking strip having edge members fitting the said outer recesses of two opposed locking flanges, and having a stitl'ening intermediate rib member fitting the said inner locking recesses of the said two flanges while extending across and sealing the seam formed by the contacting edges of said flanges, substantially as described.

4. In a metallic bilge barrel, the combina-- tion of a plurality of curved staves each provided on its ends with an oflset flange forming a seat for the head of the barrel and on its longitudinal edges with locking tone of an arch, and prevents flanges, each flange having outer and inner locking recesses openlng in opposite direct1ons; with a locking strip having edge members fitting the said outer recesses of.
